(a–e) Influence of pH on removal of Cu, Pb, Se, Zn, and Cr by adsorbents. The other conditions were kept constant during the adsorption processes. Dose = 0.1 g/L, initial conc. = 2.0 mg/L, and rpm 100/30 min. (a) Adsorption of Pb. (b) Adsorption of Cr. (c) Adsorption of Zn. (d) Adsorption of Cu. (e) Adsorption of Se.
